JOURNAL-BOX BEARING.

Specification of Letters Patent.

Application filed April 25, 1913. Serial No. 763,545.

To all whom it may concern Be it known that I, Annnnw CHRISTIAN- SON, a citizen of the United States and resident of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful, Improvement in Journal-Box Bearings; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to journal-box bearings.

In trucks for railway cars provision must be made for controlling the end thrust of the axles in the journal-boxes. and heretofore it has been customary to provide against the outward thrust by having a lug east or formed on the inside face of the top of the journal-box with which the wedge is adapted to engage and so prevent undue outward movement of the axle. This construction however has proved ineflicient in that the lug being located at the top of the journal-box could not be made deep enough to take up the thrust in line with the axial line of the axle and being at the top become worn off on its lower edge by the continual battering which it received by the outward and upward thrust of the axle, so that in time it became ineffective to properly restrain this outward movement of the axle. Unless this outward movement of the axle is restrained, it causes swaying of the car and bad riding results. i

T he object of my invention is to provide for the controlling of the end move ment of the axle farther down near the axial line of the line of the axle, so as to give a more even thrust and prevent the wearing away of the restraining lugs, and providing aconstruction in which the swaying of the car is prevented and the discomfort attend ant therewith avoided.

To these ends my invention comprises the employment of a lug or lugs on the side of the iournal box and lugs on an overhanging portion of the wedge adapted to engage the lugs on the journal-box, said lugs being so arranged that when the journal-box is jacked up the lugs on the overhanging portion of the wedge are thrown out of register with the lugs on the journal-box, so that the wedge may be readily removed.

In the accompanying drawing Figure 1 is a longitudinal section of a journal box and the journal bearing showing my invention;

Fig. 2 is a. horizontal sectional View; Fig. 3 is a front view, and Fig. 4 is a cross section on the line ll Fig. 1.

In the drawing, the numeral 2 designates asuitalole journal-box provided with the front opening 3 to be closed by the ordinary lid (not shown). Formed on the inner side wall of the journal-box 2 are the lugs at, said lugs being located at a suitable distance apart. The wedge 5 has the overhanging end portion 6 which is adapted to support the check-plate 7 interposed between said overhanging portion 6 and the end of the axle 8. The check-plate 7 has the stud 9 formed integral therewith which proieots through the opening 10 in the overhanging portion 6, and a spring 11 surrounds said stud and is interposed between the outer face of the overhanging portion 6 and the washer 12 which is held in place by the key 13 passing through the stud 9. The journalbrass 15 is interposed between the wedge 5 and the axle with an intervening layer of Babbitt or like metal 16. This bearingbrass extends down so as to inclose half or approximately half of the axle as indicated in Fig. i, and said brass in this way controls the lateral movement of the axle being interposed between said axle and the side of the iournal-box.

Extending out from the side of the over hanging portion 6 are the lugs 14 which are adapted to register with the lugs when the parts are assembled in the positions indicated in Fig. 1. These lugs 1 engaging the lugs t control the longitudinal. movement of the axle outwardly and, as said lugs are located below the top of the box and the lower lug is in substantially the axial line of the axle, it is apparent that the outward thrust of the axle is more uniformly resisted, and said lugs ofler a positive and practically continuous abutment.

When it is desired to remove the wedge 5 the ournal-box is acked up in the ordinary manner and the lugs 4L are brought up into a position above the lugs 14 and out of line with said lugs a, and the wedge can be removed without any difliculty.

By my invention I provide for the more uniform resistance of the outward thrust of the axle, while at the same time any-upward movement of the axle does not have any effect to reduce the efiiciency of my device as is the case where the lug is formed on the Copies of this patent may be obtained for overhanging portion adapted to register with the spaced lugs on said journal-box, whereby when said journal-box is raised, said lugs are thrown out of register to permit the withdrawal of said wedge.

In testimony whereof, I the said ANDREW CHRISTIAN son have hereunto set my hand.
